"Microsoft recently made a change to the licence agreement saying that a new motherboard is equal to a new computer, hence you need to purchase a new Windows licence. Here is what Microsoft has to say: "An upgrade of the motherboard is considered to result in a 'new personal computer' to which Microsoft OEM operating system software cannot be transferred from another computer. If the motherboard is upgraded or replaced for reasons other than a defect, then a new computer has been created and the license of new operating system software is required." Please note that this does not go for retail copies of Windows, but only for OEM versions.

That's all I can think of, how the heck is a new motherboard a new computer? I mean, if you want to take advantage of new things like pci-express, sata, etc, you need a new motherboard, and I for one am certainly not going to go through buying a new copy of windows just to satisfy microsoft. Also, how sure are we that this is actually serious?
